JOHN BAOKUS AND EVENS BACKUS, OF NEW' -YORK, N. Y.

PARLOR-STOVE.

Specification of Letters Patent No. 1,981, dated February 18, 1841.

T all whom it may concern Be it known that we, JOHN BAOKUS and EVENSBACKUS, of the city, county, and State of New York, have invented a new,and useful Improvement in Stoves; and we hereby declare that thefollowing is a full and accurate description thereof.

This invention is called Backuss combination stove.

The nature of this stove consists in a combination of the radiator andthe hollow base, by which combination the smoke is made to descendthrough sides or ends of the stove into the hollow base, and to ascendthence through a draft pipe at the back of the stove; and while in thispassage the smoke heats the air which is constantly passing through theradiators which are open at bottom and top to allow free way for theatmosphere of the room. I

To enable others to make and use our invention we proceed to describeits construction and operation, reference'being had to the drawinghereunto annexed and forming a part of this specification.

The stove is made of sheet iron or any other suitable material, and isbuilt in the ordinary forms of cylinder stoves, being so constructedthat the bottom of the stove rests permanently upon the top of a hollowbase, (1). The sides or ends of the stoves are so extended beyond thecylinder or fire chamber, (2), as to admit of the introduction throughthem of radiators (3), which radiators are hollow tubes open only at thetop and bottom for the admission below and escape above of thesurrounding air, which becomes heated in its passage through them. Holes(11) are cut through the partitions separating the cylinder or firechamber from the extended sides or ends of the stoves and just above thefire chamber, through which the smoke may be discharged so as to heatthe air passing through the radiators. The main or smoke pipe (4)leading from the back of the stove to the chimney, contains a damper(6), which when closed stands vertical immediately in front of the upperor discharging orifice of the draft pipe (5), and this damper (6) isused to direct the course of the smoke. When this damper is closed thesmoke passes through the holes (11), and when it is open the smokepasses directly through the main or smoke pipe into the chimney. Thedraft pipe (5) stands vertically behind the stove, and extends only fromthe top of the hollow base (1), to the bottom of the main or smoke pipe(4.). Another damper (7) is placed in the draft pipe just below itsupper orifice, which damper is closed when number 6 is open and viceversa. The hollow base (1) contains partitions (13) by which the smoke,when thrown upon the raidators by closing damper 6 and opening damper 7,is turned nearly or quite to the front of the stove before it can makeits escape through the draft pipe behind.

Opcmti0n.Fire being kindled in the cylinder or fire chamber (2), uponthe hearth or grate (12), damper 7 is closed and damper 6 opened. Thiscreates an immediate draft from the fire through the main or smoke pipe,and a rapid discharge of the smoke. When it is required to heat theradiators, damper 6 is closed and damper 7 opened. The smoke now passesthrough the holes (11) into the extended sides or ends of the stove thatcontains the radiators which it completely surrounds. It then descendsinto the hollow -basepasses around the partitions (l8)enters the draftpipe at its bottom-ascends through it to the main or smoke pipe (4), andthence escapes to the chimney. By this manner of conducting off thesmoke, it heats the radiators and of course the air which passes throughthem continually from bottom to top, so that the atmosphere of a room inwhich one of these stoves is placed, is continually warmed by a constantdischarge of heated air from the stove itself, and while this dischargecontinues there is less combustion of fuel going forward in consequenceof the subdued and controlled draft downward and upward.

Dcscm'ptc'on of the (Zrm0ings.Figure A, is a front view and perspectivedrawing of the stove. Fig. B, is an end or side view of the same, andalso in perspective. Fig. C, is a sectional representation of the hollowbase with its partitions (13). Fig. D, represents the radiator. Fig. E,is a sectional drawing showing the positions of the hollow base, thefire chamber, radiators, the

course of the smoke when discharged upon the radiators, whlch course 18indicated by the letters a, Z), 0, cl, as the stand.

N0. 1 is the hollow base of the stove.

No. 2 is the cylinder or fire chamber; 3, 3, the radiators passingthrough the body and base of the stove and open at both ends to admitthe free passage of the surrounding air from the bottom to the top; theair be' ing heated in its passage through.

4 is the main or smoke pipe.

5 is the draft pipe leading from the top ofthe hollow base to the bottomof the main or Smoke pipe, and opening into both.

.6 is the damper in the main or smoke pipe, and placed directly in frontof the upper orifice of the draft pipe.

7 is the damper in the draft pipe,i and is placed just below the upperorifice; 8, the

door of the stove where the fuel is put in; 9, a small draft door belowthe hearth or grate; 10, the ash pan below the fire chamber; 11, holesin the partitions between the fire chamber and the extended Sides orends radiators and the base.

and passing through the hollow base and 2 draft pipe for the purpose ofheating the The course is indicated beginning at a, and ending orpassing 01f at (Z.

What we claim as our invention and desire to have secured to us byLetters Patent, is The combination of the hollow base and the radiators.
